If you've ever tried to engage in some jolly Dark Souls cooperation with one of your friends, you'll know that it's not very straightforward. Why? Because you're meant to play with strangers. You're meant to have your bacon saved by unknowns. That's what the game wants. But to hell with the game, because one smart modder has changed all that.
DSCfix - otherwise known as Dark Souls Connectivity Fix - aims to "improve the online experience when attempting to engage in jolly cooperation with friends." It means that direct connections to friends is now a very real possibility, without having to play summon roulette for potentially hours beforehand. You'll need to use it in concert with DSfix, and it works by prioritising your GFWL friends before casting its nets to the wider player base.
All the instructions for how to install is in the mod notes . It's the work of one M0tah. Thanks, M0tah.
